==Overview==
[[Mitral stenosis]] is narrowing of the heart valve between the two left chambers of the heart ([[left atrium]] and [[left ventricle]]).
==Pathophysiology==
* The hallmark anatomical picture in mitral stenosis is commisural fusion.
* Because of closure of the [[mitral valve]] pressures build up in the left atrium which reflect back to the pulmonary bed.
* This build up of pressures in the pulmonary bed causes [[pulmonary hypertension]] causing [[right heart failure]].
* Left ventricle is unaffected in pure mitral stenosis.
==Causes==
The cause of [[mitral stenosis]] is almost always [[rheumatic heart disease]].
==Differentiating Mitral stenosis from other Diseases==
Mitral stenosis should be differentiated from:
* [[Cor triatriatum]]
* [[Atrial myxoma]]
* Pulmonary vein obstruction
==Natural History==
Mitral stenosis is a disease of plateaus.  It is intermittently progressive and has a prolonged clinical course before becoming severe.
